To guarantee that students have access to safe drinking water at school, we conduct water testing at every school on a five year cycle. We have set an action level of 10 ppb when testing 250 milliliter of first draw samples from water outlets in schools. Outlets are removed from service immediately if results show lead levels above 10 ppb. An action plan is developed for each outlet that exceeds 10 ppb. Principals are provided with letters and water results to send home with students. All water testing results are posted on line for public view.
